Placa revestida dura: Types of Hardfacing Layers Used in Wear-Resistant Steel Plates
Hardfaced plate is a composite wear-resistant steel product manufactured by depositing a hard alloy layer onto a carbon steel or low-alloy steel base plate. The performance of the plate is mainly determined by the type of hardfacing layer, which controls hardness, resistencia al desgaste, resistencia al impacto, y vida útil.
Different welding overlay systems are selected based on working conditions such as abrasion, impacto, temperatura, y corrosión.
1. Main Types of Hardfacing Layers
| Hardfacing Type | Main Composition | Características clave |
|---|---|---|
| Recubrimiento de carburo de cromo | fe + do + cr (high chromium carbides) | Excelente resistencia a la abrasión, most common type |
| Complex carbide overlay | cr + Nótese bien + Mes + do | Higher toughness and improved wear resistance balance |
| Recubrimiento de carburo de tungsteno | WC + Ni/Fe matrix | Dureza extremadamente alta, best for severe abrasion |
| Nickel-based overlay | En + cr + B + Y | Excellent corrosion and high-temperature resistance |
| Manganese-based overlay | High Mn + C alloy | Work hardening under impact conditions |
2. Performance Comparison of Different Overlay Layers
| Tipo | Resistencia al desgaste | Resistencia al impacto | Aplicación principal |
|---|---|---|---|
| Carburo de cromo | muy alto | Medio | Minería, cemento, manejo del carbón |
| Complex carbide | Alto | Alto | Condiciones de desgaste mixtas |
| Carburo de tungsteno | Extremely high | Bajo a medio | Abrasión por deslizamiento severa |
| Nickel-based | Medio | Alto | Temperatura alta & corrosión |
| Manganese-based | Medio | muy alto | Impact-dominated wear |
3. Why Different Hardfacing Layers Are Needed
- Different wear mechanisms: abrasión, impacto, erosión, corrosión
- Different working environments: dry, wet, high temperature, corrosivo
- Different service life requirements: short-term vs long-term protection
There is no single hardfacing layer that fits all conditions; selection must match the actual application.
4. Layer Structure of Hardfaced Plate
| Capa | Función |
|---|---|
| capa de revestimiento duro | Provides wear resistance |
| Transition layer (if applicable) | Mejora la fuerza de unión |
| Placa base de acero | Provides structural support |
5. Selection Guidelines for Hardfacing Layers
| Condición | Recommended Layer Type |
|---|---|
| Alta abrasión (carbón, cemento, mineral) | Recubrimiento de carburo de cromo |
| Mixed impact + abrasión | Complex carbide overlay |
| Extreme sliding wear | Recubrimiento de carburo de tungsteno |
| High temperature corrosion | Nickel-based overlay |
| Strong impact loading | Manganese-based overlay |
